Mine so far include" I've Got Your Number by Sophie Kinsella a contemporary with humor and romance, Breathe by Kristen Ashley (I went on a huge K.A. glom and it was hard to pick my favorite between Mystery Man, Motorcycle Man and Breathe), The Governess Affair, a historical by Courtney Milan, and Her Best Worst Mistake by Sarah Mayberry.

I liked Sophie Kinsella's book too as well as "Edenbrooke" by Julianne Donaldson, "Overseas" by Beatriz Williams, "The Hypnotist's Love Story" by Liane Moriarty, "Practically Wicked" by Alissa Johnson.

Beautiful Bad Man by Ellen O'Connell, Defiant by Pamela Clare and Dragon Ship by Lee and Miller. This surprised me when I looked at my DIK list because I've been on such a mystery glom the past couple of months. My favorite mystery was Kindness Goes Unpunished by Craig Johnson (a Longmire book)--copyright 2007. I am about 1/3 through The Anatomist's Wife, which is so far a DIK.

I would recommend The Summer of Living Dangerously by Julie Cohen although it's not as light-hearted and the title is somewhat unsuitable IMO.
It was one of my favourite reads this year.

Fifty Shades of Grey by EL James
The Undomestic Goddess by Sophie Kinsella
Broken by Megan Hart
Cecily by Clare Darcy

Slightly Scandalous by Mary Balogh
The Defiant Hero by Suzanne Brockmann
Arabella by Georgette Heyer
Slightly Dangerous by Mary Balogh

I saw a few mentions of Edenbrooke and so I decided to check it out and so glad I did. It was so romantic, love letters, poems, twirling. I was discouraged by the price, $9.59 for kindle, for a debut author. IMO the price was worth it. I see she has a new book coming out, hopefully in Spring 2013 called Blackmoore and I don't think its related to Edenbrooke. I look forward to her next book but hope it isn't as expensive!
